Did not realize until now there was such as thing as a "FLoating CPU Window".... but I did find it and it does show all 8 (4 real/4 virtual). What I had been referring to was a the bottom of the main Activity WIndow, where you have the tabs for [CPU] [System Memory] [Disk Activity] [Disk Usage] [Network]

But upon doing a bit more research... OSX combines THAT display into one, if there are more than 4 cores (real or virtual)

To be pedantic about it, it's showing you 8 virtual CPUs. Were you to top out one physical core, the monitor would show two CPU bars topped out.

It's worth remembering that if your RS app enters a tight loop which would consume 100% of a single CPU, it tops out one virtual CPU, which is just 1/8 (12.5%) of the Y axis extent on the combined graph of a modern iMac.
